How to connect a 4K, 8K, or HDR device to your Roku TV

What you need for HDR

To enjoy HDR or watch in 4K/8K, your setup must meet the following requirements:

• A Roku TV that supports 4K or 8K resolution
• A Roku TV that supports HDR (HDR10, Dolby Vision, etc.)
• A connected device that supports, 4k, 8k, or DR
• A high-speed HDMI cable made for 4K or 8K
• The right HDMI port settings on your Roku TV

Note: Some gaming consoles support HDR but not HDCP 2.2. This can cause problems with 4K or HDR. HDCP is a type of copy protection your TV needs to play this content.

If HDR is not working, try changing the HDMI mode

Sometimes the picture looks dull, or HDR doesn’t work. Try changing the HDMI mode for the port your device is plugged into.

• Auto – Best choice for most devices. TV chooses the best setting.
• Compatibility – Use for older devices (like older Blu-ray players). May lower picture quality.
• Standard – Best for newer devices that support 4K HDR and gaming features.

Note: If HDR or gaming features aren’t working, try switching to Standard.

If the picture is blank or not displayed correctly when switching your Roku TV to the input used by the device, try the following:

Which kind of HDMI cable is needed?

HDMI cables come in different versions. Here’s what each version supports:

• HDMI 1.4 – Works for most cable or satellite boxes. Supports 4K at 30 frames per second (fps).
• HDMI 2.0 – For 4K streaming or Blu-ray. Supports 4K at 60 fps.
• HDMI 2.1 – Best for gaming and the newest 8K devices. Supports 4K at 120 fps and 8K at 60 fps.

Make sure your HDMI cable matches your device. Older cables might not support newer features like HDR or high frame rates.
